Since restoring files involves the use of one or more tapes on a tape
device, you must complete the following three steps before issuing the
RESTORE command:
Locate the Necessary File or Files |
 |
Search your tape library for the STORE tape(s) containing the files
you want to restore. If you do not know where the tape file(s) are, you
can use the RESTORE command to list the contents of the tape. Refer
to "When RESTORE is Complete", later in this chapter.
Checking for Duplicate Filenames |
 |
Before you RESTORE a file from a STORE tape, check whether a
disk file with the same name already exists. If a file with the same
name resides in the account and group you are restoring to, the disk
file is overwritten by the backup file during the RESTORE process by default.
 |
 |  |
 |
 | CAUTION: If you do not wish to lose current disk files with the same fully qualified
filenames as the files you are restoring, use the KEEP parameter of the RESTORE command. |
 |
 |  |
 |
To check for duplicate filenames, use the LISTF command
for each file you intend to RESTORE. For example:
:LISTF filename.groupname.accountname
|
Use wildcard characters to represent a set of files.
Refer to "Using Wildcard Characters", in Chapter 5, "Storing Files," for
details. For example, the following LISTF command lists all
files in the PUB group of the RESEARCH account:
If at least one file exists, the system prints the filename at your terminal.
If files matching the search criteria do not exist,
the system prints the message:
NON-EXISTENT FILE (CIERR 907)
|
Preparing the Media and the Backup Device |
 |
Prepare the STORE tape following the instructions in
Chapter 3, "Preparing Storage Devices." Make
sure that you protect the files on the tape by removing the write
ring. Mount the STORE tape on your tape device.
